Multiplication Commutativity Issue within sum{ }

[jlepird]

After playing around with the vectorization stuff, I noticed that the following script

using JuMP
m = Model()
@defVar(m,x[1:10])
c = [1,2,3,4,5,6,7,8,9,10]
@addConstraint(m,sum{x[i]*c[i],i=1:10} < 1)

returns the error "No method *(Variable,) found in macros.jl". However, the following script works fine:

using JuMP
m = Model()
@defVar(m,x[1:10])
c = [1,2,3,4,5,6,7,8,9,10]
@addConstraint(m,sum{c[i]*x[i],i=1:10} < 1)

Yep, thanks for reporting. This is a known issue.

Finally resolved. Main docs still need to be updated, but we should wait until 0.4 is released for that.
